Fernette??

Came across this while doing research. It was the name of one of the authors on a book.
What do you guys think? Do you like it? It feels like it sounds like a liquor but I can't put my figure on it.
Fancier version of Fern? Or a completely separate name?
(I goggled it, thought not super thoroughly and only came up with this particular author).
I don't know what I think but I figured I'd share.
